Description

BACKGROUND OF THE INVENTION

Field of invention

The present invention relates to a start control device of a vehicle and, more particularly, to a method and an apparatus adapted to control a start process of a vehicle and capable of controlling the speed of the vehicle during the initial start process.

Description of the related art

In general, a vehicle is propelled by transmitting power generated by an engine to a drive wheel through a power output device. The engine receives air and fuel from outside and burns a mixture of air and fuel in a combustion chamber to generate power.

When a driver of the vehicle requests the vehicle to be started with a start button or an ignition key, the engine starts spontaneously so that the engine speed (min ^-1 ) increases / increases to an idling speed before starting.

In the event of a cold start or if the voltage of a battery is insufficient, the vehicle keeps the idling speed at a high speed (min ^-1 ) to increase the load on the engine. For example, the idle speed of the engine for a normal start can be about 550-800 min ^-1 , while the idle speed of the engine for a cold start can be about 1000-1800 min ^-1 .

If a driver of the vehicle who is inexperienced in cold starting does not check the idling speed of the engine and releases a brake pedal immediately after being asked to start the vehicle, the vehicle can start moving quickly due to the high speed of the vehicle caused by the high speed, so that the The likelihood of an accident increases.

In addition, the driver may be surprised or embarrassed because the speed of the vehicle increases rapidly. Since the vehicle starts running without the driver's will, the driver may feel that the quality of the vehicle is poor.

The information contained in said “Background of the Invention” section is only intended to provide a better understanding of the general background of the invention and should not be taken as recognition or any form of suggestion that this information represents the state of the art already known to a person skilled in the art.
